Create and Update an Unlocked Package

When you’re ready to test or share your package, use the sf package create command to create a package.

If you are using a namespace, specify the package namespace in the sfdx-project.json file. To learn more, see Understanding Namespaces.

To create the package, change to the project directory. The name becomes the package alias, which is automatically added to the project file. You can choose to designate an active Dev Hub org user to receive email notifications for Apex gacks, and install, upgrade, or uninstall failures associated with your packages.

1sf package create --name "Expenser App" --package-type Unlocked --path  \
2"expenser-main" --target-dev-hub my-hub --error-notification-username me@devhub.org

The output is similar to this example.

1sfdx-project.json has been updated.

Update the Package

To update the name, description, or the user to receive error notifications of an existing package, use this command.

1sf package update --package "Expense App" --name "Expense Manager App" \
2--description "New Description" --error-notification-username me2@devhub.org

You can’t change the package namespace or package type after you create the package.
